Abstract
Description
Technical Field
[0001] The utility model relates to a withering device, in particular to a precisely controlled tea withering device. Background Art
[0002] Withering, also known as "withering carving", is the name of the tea-making process. The picked fresh leaves are spread out to a certain thickness and dried in the sun to make them wilt. During the withering process, the fresh leaves undergo a series of changes: the moisture content decreases, the leaves become soft instead of brittle and hard, making them easier to roll into strips, and the activity of enzymes in the leaves increases, which promotes the decomposition and transformation of fresh leaf components such as starch, protein, and insoluble protopectin, generating effective substances such as glucose, amino acids, and soluble pectin that are beneficial to the quality of the finished tea. Polyphenols are also oxidized to varying degrees.
[0003] The existing equipment puts the tea leaves into a drying box and then starts a heater to air-dry them, which accelerates the withering of the tea leaves. However, this equipment requires opening the drying box intermittently to turn the tea leaves over so that the tea leaves wither fully. If the tea leaves are not turned over manually, the tea leaves piled at the bottom will be blocked and cannot absorb heat well, which will eventually lead to uneven withering of the tea leaves and affect the overall quality of the tea products.

DETAILED DESCRIPTION
[0019] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.
[0020] Embodiment: A precisely controlled tea withering device, such as Figure 1-Figure 5 As shown, it includes a drying box 1, a safety door 2, a controller 3, a heater 4, a support block 5, an electric push rod 6, a slot 7, a loading frame 8, a temperature sensor 9 and an LED lamp 10. The front side of the drying box 1 is rotatably connected to the safety door 2 through a hinge, the left side of the top of the drying box 1 is connected to the controller 3 through bolts, the middle of the top of the drying box 1 is connected to the heater 4 through bolts, the air outlet of the heater 4 is located at the top of the drying box 1, and ventilation holes are left on both sides of the bottom of the drying box 1. Two support blocks 5 are welded on the left and right sides of the bottom of the drying box 1. The left and right sides of the bottom of the drying box 1 are connected to the electric push rod 6 through bolts. Rod 6, the electric push rods 6 on both sides are respectively located between the two support blocks 5 on the same side, and the telescopic rods of the two electric push rods 6 are welded with card slots 7. The card slots 7 on both sides are respectively slidably connected between the two support blocks 5 on the same side, and a loading frame 8 is placed between the middle parts of the two card slots 7 for sliding back and forth. There is a three-centimeter space between the two card slots 7 for the loading frame 8 to move up and down. A temperature sensor 9 is connected to the rear side of the drying box 1 by bolts, and LED lights 10 are connected to the top sides of the drying box 1 by bolts. The controller 3 is electrically connected to the heater 4, the electric push rod 6, the temperature sensor 9 and the LED light 10.
[0021] like Figure 3 and Figure 5 As shown, a protective net 11 is also included. The protective net 11 is welded between the upper parts of the two card slots 7, and the protective net 11 is located above the charging frame 8.
[0022] like Figure 3 and Figure 5 As shown, a rubber block 12 is also included, and the rubber blocks 12 are fixedly connected to both sides of the bottom of the charging frame 8.
[0023] like Figure 1 and Figure 3 As shown, an air duct 16 is also included. The air duct 16 is welded to the vent on the right side of the bottom of the drying box 1, and the other end of the air duct 16 is located above the heater 4.
[0024] When the tea leaves need to be withered, it is necessary to first rotate the safety door 2 clockwise to open it, then drag the loading frame 8 forward by hand, then evenly stack the tea leaves in the loading frame 8, and then put the loading frame 8 back between the two card slots 7, then reset the safety door 2, and start the LED lamp 10 and the heater 4 through the controller 3. The LED lamp 10 is used to simulate sunlight to accelerate the withering process of the tea leaves. The heater 4 draws air from the top of the drying box 1 into the interior thereof, and sends it into the drying box 1 after heating, so as to dry the tea leaves and reduce the moisture in the tea leaves. Then, a part of the air flow returns to the air through the opening on the left side of the drying box 1, and the other part flows into the air duct 16 through the opening on the right side of the drying box 1, and then returns to the top of the heater 4 through the air duct 16 and is re-inhaled into the interior thereof, and then returns to the drying box 1 again, thereby forming an air flow loop. During this process, the temperature sensor 9 will detect the temperature in the drying box 1 in real time and transmit the data to the controller 3. The temperature in the drying box 1 can be viewed in real time on the controller 3, so as to adjust the heater according to the temperature required for withering of different tea leaves. 4 and the power of the LED lamp 10, the temperature in the drying box 1 is controlled within a suitable range, and at the same time, the electric push rods 6 are started by the controller 3, and the two electric push rods 6 drive the card slots 7 on both sides to move up and down quickly. When the card slot 7 moves downward from the highest point, there is a three-centimeter space between the two card slots 7 for the loading frame 8 to move up and down. The loading frame 8 will shake up and down in the card slot 7 with the rubber block 12 and the tea leaves. At this time, the rubber block 12 has a buffering effect on the loading frame 8, reducing the noise caused by the shaking. The protective net 11 between the upper parts of the two card slots 7 The tea leaves can be prevented from falling out of the loading frame 8. The tea leaves in the loading frame 8 can be turned over by shaking to make the withering effect more uniform. When the tea leaves are completely withered, the heater 4, the electric push rod 6 and the LED light 10 need to be turned off in sequence through the controller 3, and then the safety door 2 is opened clockwise, and the loading frame 8 is dragged out to the front side, and then the tea leaves in the loading frame 8 are collected, and finally the loading frame 8 and the safety door 2 are reset in sequence. At this point, the withering of the tea leaves is completed. If more tea leaves are to be withered, the above operation can be repeated.
[0025] like Figure 3 As shown, it also includes a partition 13, a scraper 14 and a pull block 15. The partition 13 is symmetrically fixed to the bottom of the drying box 1. The two partitions 13 are located between the two electric push rods 6. The scraper 14 is slidably connected between the two partitions 13. The scraper 14 contacts the bottom of the drying box 1, and a pull block 15 is welded on the top of the scraper 14.
[0026] When the tea leaves are withering, it is inevitable that some broken leaves will fall into the bottom of the drying box 1. When the broken leaves at the bottom of the drying box 1 need to be cleaned, it is necessary to first open the safety door 2 clockwise, then grab the pull block 15 with your hand, and then pull the pull block 15 forward. The pull block 15 drives the scraper 14 to move forward, and the scraper 14 will bring the broken leaves at the bottom of the drying box 1 forward, and then manually collect and clean the scraped broken leaves, and then reset the pull block 15, the scraper 14 and the safety door 2.
[0027] like Figure 1 As shown, it also includes a glass plate 17 and a universal wheel 18. The safety door 2 is provided with a glass plate 17, and the four corners of the bottom of the drying box 1 are welded with universal wheels 18.
[0028] The user can check the situation in the drying box 1 through the glass plate 17 on the safety door 2, so that when an unexpected situation occurs, it is convenient to deal with it in the first time.
[0029] The above description is only an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent replacement made within the principle of the present invention shall be included in the protection scope of the present invention. The contents not elaborated in the present invention belong to the existing technology known to the technicians in this professional field.
